Description

Stangenverschluß mit Erdungseinrichtung Rod lock with earthing device
B e s c h r e i b u n gDescription
Die Erfindung betrifft einen Stangenverschluß insbesondere für Schaltschranktüren oder dergleichen, mit einem an der Tür befestigbaren metallischen oder elektrisch leitenden Schloßkasten und wenigstens einer darin unter der Wirkung eines von einer Betätigung drehbaren Ritzels längsverschiebbar angeordneten Schloßstange, wobei der Schloßkasten bei seiner Montage an der Tür über eine Erdungseinrichtung in leitenden Kontakt mit der Tür gebracht wird.The invention relates to a rod lock, in particular for control cabinet doors or the like, with a metal or electrically conductive lock case which can be fastened to the door and at least one lock bar arranged therein under the action of a pinion which can be rotated by an actuation, the lock case being mounted on the door via a Earthing device is brought into conductive contact with the door.
Ein Stangenverschluß mit den vorgenannten Merkmalen ist in dem DE GM 90 16 696 beschrieben; soweit in der Regel die Türen eines Schaltschrankes mit einer Lackschicht versehen sind, ist als Erdungsmaßnahme bei dem bekannten Stangenverschluß an dem Schloßkasten eine Erdungsfederscheibe vorgesehen, die bei der Montage des Schloßkastens an der Tür zwischen dem Schloßkasten und der Tür zu liegen und unter Klemmwirkung durchA rod lock with the aforementioned features is described in DE GM 90 16 696; as far as the doors of a control cabinet are usually provided with a layer of lacquer, a grounding spring washer is provided as a grounding measure in the known rod lock on the lock case, which during assembly of the lock case on the door between the lock case and the To lie in the door and under clamping action
Befestigungsmittel durch Muttern oder Schrauben kommt, und einen in Richtung auf die Tür vorgebogenen Vorsprung aufweist, der beim Festziehen des Befestigungsmittels in eine Strecklage gelangt und dabei mit an ihm angeordneten Spitzen oder Kanten die Lackschicht wegschabt, so daß sich eine leitende Verbindung zwischen der Erdungsfederscheibe, damit zwischen dem Schloßkasten und der Metallfläche der Tür einstellt.Fastener comes through nuts or screws, and has a protrusion bent toward the door, which reaches a stretched position when the fastener is tightened and scrapes away the lacquer layer with tips or edges arranged on it, so that there is a conductive connection between the earthing spring washer, thus adjusts between the lock case and the metal surface of the door.
Mit der bekannten Erdungsmaßnahme für den Schloßkasten ist der Nachteil verbunden, daß es sich bei der vorgesehenen ErdungsfederScheibe um einen kleines, zusätzliches Bauteil handelt, welches bei der Montage des Stangenverschlusses schwierig zu handhaben ist. Als weiterer Nachteil ist zu nennen, daß die Herstellung der leitenden Verbindung allein von der Befestigung des Schloßkastens an der Tür abhängig ist, weil nur durch das Anziehen der Befestigungsmittel die notwendige Kratzspur hergestellt wird. Diese Erdungsverbindung ist demnach nicht immer ausreichend sicher. Es kommt hinzu, daß die Kratzspur während der Lebensdauer des Schaltschrankes korrodieren kann, so daß die Erdungsmaßnahme unwirksam werden kann.The known earthing measure for the lock case has the disadvantage that the earthing spring washer provided is a small, additional component which is difficult to handle when the rod lock is being installed. Another disadvantage is that the production of the conductive connection depends solely on the fastening of the lock case to the door, because the necessary scratch mark is produced only by tightening the fastening means. This ground connection is therefore not always sufficiently secure. In addition, the scratch mark can corrode during the service life of the control cabinet, so that the grounding measure can become ineffective.
Der Erfindung liegt daher die Aufgabe zugrunde, die Montage eines Stangenverschlusses mit einer Erdungseinrichtung zu vereinfachen und die Wirksamkeit der Erdungseinrichtung insgesamt zu verbessern.The object of the invention is therefore to simplify the assembly of a rod lock with an earthing device and to improve the effectiveness of the earthing device as a whole.
Die Lösung dieser Aufgabe ergibt sich einschließlich vorteilhafter Ausgestaltungen und Weiterbildungen der Erfindung aus dem Inhalt der Patentansprüche, welche dieser Beschreibung nachgestellt sind.This object is achieved, including advantageous refinements and developments of Invention from the content of the claims which follow this description.
Die Erfindung sieht in ihrem Grundgedanken vor, daß eine zwischen Schloßkasten und Tür angeordnete und im Klemmsitz gehaltene Erdungsplatte mit einem über die Kontur des Schloßkastens hervorstehenden Ansatz zur Aufnahme einer die leitende Verbindung mit der Tür herstellenden Schraube mit Schabwirkung vorgesehen ist, und daß die Erdungsplatte wenigstens zwei geringfügige Materialerhöhungen als Auflagerfläche für den Schloßkasten aufweist. Mit der Erfindung ist der Vorteil verbunden, daß bei der Montage des Stangenverschlusses die zwischen dem Schloßkasten und der Tür anzuordnende Erdungsplatte einfach zu handhaben ist. Soweit durch den an der Erdungsplatte befindlichen Ansatz eine Schraube senkrecht zur Türebene hineinzudrehen ist, ist auch die über die Schraube aufzubringende Kratzwirkung einfacher auszuüben und sicherer durchzuführen. Soweit an der Erdungsplatte zusätzlich Materialerhöhungen als Auflager für den Schloßkasten vorgesehen sind, ergibt sich daraus eine erhöhte Flächenpressung zwischen dem Schloßkasten und den Materialerhöhungen der Erdungsplatte, so daß an den Auflagerstellen eine Korrosion und damit eine Unterbrechung der Erdungswirkung vermieden ist.The invention provides in its basic concept that a grounding plate arranged between the lock case and the door and held in the clamp seat is provided with a protruding projection over the contour of the lock case for receiving a screw with a scraping effect that creates the conductive connection with the door, and that the grounding plate at least has two slight increases in material as a bearing surface for the lock case. The invention has the advantage that the earthing plate to be arranged between the lock case and the door is easy to handle when the rod lock is installed. Insofar as a screw can be screwed in perpendicularly to the plane of the door due to the attachment on the grounding plate, the scratching effect to be applied via the screw is also easier to carry out and safer to carry out. Insofar as additional material increases are provided as supports for the lock case on the earthing plate, this results in an increased surface pressure between the lock case and the material increases in the earth plate, so that corrosion and thus an interruption of the earthing effect is avoided at the support points.
Nach einem Ausführungsbeispiel der Erfindung ist vorgesehen, daß Schloßkasten und Erdungsplatte über Formschlußgestaltungen aneinander orientiert sind, wodurch die Montage weiter erleichtert ist. In zweckmäßiger Form kann nach einem Ausführungsbeispiel der Erfindung die die Erdung herstellende und in die Erdungsplatte einschraubbare Schraube als eine Schraube mit Schneidkerb ausgebildet sein.According to one embodiment of the invention, it is provided that the lock case and grounding plate are oriented to one another via form-fitting designs, which further facilitates assembly. In an expedient form, according to one exemplary embodiment of the invention, the screw which produces the earthing and can be screwed into the earthing plate can be designed as a screw with a cutting notch.
Ein weiterer Aspekt der Erfindung besteht darin, nicht nur den Schloßkasten zu erden, sondern auch dafür Sorge zu tragen, daß die in dem Schloßkasten laufende, wenigstens eine Schloßstange oder bei üblicher Ausführung eines Stangenverschlusses beide in dem Schloßkasten laufenden Schloßstangen geerdet sind, weil aufgrund der Antriebsmechanik der perforierten Schloßstangen über das in dem Schloßkasten gelagerte Ritzel keine exakte Kontaktierung von der Tür über den Schloßkasten bis zur Schloßstange bzw. der daran noch angehängten Verriegelungsstange sichergestellt ist. Daher sieht die Erfindung zusätzlich vor, daß zur Erdung der wenigstens einen Schloßstange in dem Schloßkasten ein Schleifkontakt vorgesehen ist.Another aspect of the invention is not only to ground the lock case, but also to ensure that the lock bars running in the lock case, at least one lock bar or, in the usual implementation of a bar lock, both lock bars running in the lock case are grounded because of the Drive mechanism of the perforated lock bars on the pinion mounted in the lock case no exact contact from the door via the lock case to the lock bar or the locking bar still attached to it is ensured. Therefore, the invention additionally provides that a sliding contact is provided for grounding the at least one lock rod in the lock case.
Nach einem ersten Ausführungsbeispiel dieses Erfindungsaspektes kann vorgesehen sein, daß zwischen die Schloßkastenteile ein Federblech mit gegen die Schloßstange anliegenden Federvorsprüngen eingelegt ist, wobei das Federblech in seiner zu den Schloßkastenteilen parallelen Erstreckung eine sich beim Einspannen zwischen die Schloßkastenteile streckende Wölbung aufweist.According to a first embodiment of this aspect of the invention it can be provided that a spring plate with spring projections resting against the lock rod is inserted between the lock case parts, the spring plate having a curvature stretching when clamped between the lock case parts in its extension parallel to the lock case parts.
In einer alternativen Ausführungsform der Erdung der Schloßstangen kann vorgesehen sein, daß zwischen einer Wand des Führungskanals und der Schloßstange eine an dem Schloßkasten festgelegte, vorgespannte und durch ihre Vorspannung in Anlage an der Schloßstange gehaltene Flachbandfeder angeordnet ist.In an alternative embodiment of the grounding of the lock rods it can be provided that one between the wall of the guide channel and the lock rod Lock case is fixed, biased and held by its bias in contact with the lock rod ribbon spring.
Eine weitere Möglichkeit besteht darin, daß zwischen der Erdungsplatte und dem Schloßkasten eine in Richtung auf den Schloßkasten vorgespannte Erdungsfeder eingespannt ist, die mit einem Federarm durch einen in dem Schloßkasten ausgebildeten Durchbruch hindurchgreift und federnd in Anlage an der im Schloßkasten laufenden Schloßstange gehalten ist, wobei nach einer Ausführungsform der Erfindung die Erdungsfeder an die der Erdung der Erdungsplatte dienende Schraube angeschlossen sein kann.Another possibility is that between the earthing plate and the lock case a biased in the direction of the lock case earthing spring is clamped, which engages with a spring arm through an opening formed in the lock case and is resiliently held in contact with the lock rod running in the lock case, whereby According to one embodiment of the invention, the grounding spring can be connected to the screw serving to ground the grounding plate.

In dem in Fig. 1 dargestellten Schloßkasten 10 sind zwei kurze Schloßstangen 11 längsverschiebbar geführt, wobei an die Schloßstangen 11 zusätzliche Verriegelungsstangen 30 angehängt sind. Der Schloßkasten 10 ist über in Schraublöcher 12 einschraubbare, nicht dargestellte Befestigungsmittel an einem ebenfalls nicht dargestellten Türblatt zu montieren. Zwischen dem Schloßkasten 10 und dem nicht dargestellten Türblatt wird eine Erdungsplatte 13 derart angeordnet, daß die Erdungsplatte 13 bei montiertem Stangenverschluß zwischen dem Schloßkasten 10 und dem Türblatt zu liegen kommt. Die Erdungsplatte 13 weist einen über die Kontur des Schloßkastens herausragenden Ansatz 14 auf, in welchen eine Schraube 15 mit Schabwirkung eingeschraubt ist, die in montiertem Zustand über das Wegkratzen der Lackierung die leitende Verbindung zwischen dem metallischen Türblatt und dem Schloßkasten herstellt.In the lock case 10 shown in FIG. 1, two short lock bars 11 are guided so as to be longitudinally displaceable, with additional locking bars 30 being attached to the lock bars 11. The lock case 10 is to be mounted on a door leaf, also not shown, via fastening means (not shown) which can be screwed into screw holes 12. Between the lock case 10 and the door leaf, not shown, an earth plate 13 is arranged such that the earth plate 13 comes to rest when the rod lock is mounted between the lock case 10 and the door leaf. The grounding plate 13 has a projection 14 protruding over the contour of the lock case, into which a screw 15 with a scraping effect is screwed in, which in the assembled state produces the conductive connection between the metallic door leaf and the lock case by scraping away the paint.
Wie Fig. 2 deutlicher zu entnehmen ist, weist das Erdungsblech 13 eine zentrale Öffnung 17 zum Durchtritt des Betätigungsdorn eines nicht dargestellten, zum Stangenverschluß gehörigen Betätigungsmittels auf, ebenso Schraublöcher 18, die bei der Montage in eine fluchtende Lage mit den Schraublöchern 12 des Schloßkastens 10 gebracht werden. Zur Erleichterung der Montage sind die Schraublöcher 18 der Erdungsplatte 13 mit einem Kragen 19 versehen, der in die Schraublöcher 12 des Schloßkastens 10 eingreift und so eine formschlüssige Orientierung zwischen Schloßkasten 10 und Erdungsplatte 13 herstellt.As can be seen more clearly in FIG. 2, the grounding plate 13 also has a central opening 17 for the passage of the actuating mandrel of an actuating means (not shown) belonging to the rod lock Screw holes 18 which are brought into alignment with the screw holes 12 of the lock case 10 during assembly. To facilitate assembly, the screw holes 18 of the grounding plate 13 are provided with a collar 19 which engages in the screw holes 12 of the lock case 10 and thus creates a positive orientation between the lock case 10 and the grounding plate 13.
In den vier Eckbereichen weist die Erdungsplatte 13 jeweils leicht über ihre Ebene hervorstehende Materialerhöhungen 16 auf, die als Auflager für den Schloßkasten 10 dienen, so daß bei montiertem Schloßkasten der Schloßkasten 10 mit einer vergleichsweise hohen Flächenpressung auf den Materialerhöhungen 16 der Erdungsplatte 13 auflagert, so daß in diesem Bereich Korosion vermieden ist.In the four corner areas, the grounding plate 13 each has material protrusions 16 protruding slightly above its level, which serve as supports for the lock case 10, so that when the lock case 10 is mounted, the lock case 10 rests on the material increases 16 of the grounding plate 13 with a comparatively high surface pressure that corrosion is avoided in this area.
In Fig. 3 ist ein erstes Ausführungsbeispiel der zusätzlich vorgesehenen Erdungsmaßnahme für die wenigstens eine Schloßstange 11 dargestellt, wobei in einer Wand 28 des Führungskanals für die Schloßstange, hier dem Deckel, eine Flachbandfeder 21 angeordnet ist, die mit ihren Enden 22 in Öffnungen 23 in der Wand 28 des Schloßkastens 10 eingehakt und festgelegt ist. Wie sich aus Fig. 3a im einzelnen entnehmen läßt, ist die Flachbandfeder 21 in Richtung auf das Innere des Schloßkastens 10 vorgebogen, so daß sie Kraft ihrer Federspannung in Anlage an der Stirnseite der in dem Schloßkasten 10 laufenden Schloßstange 11 gehalten ist. Damit ist eine sichere Erdungsverbindung von der Verriegelungsstange 30 über die Schloßstange 11 und den Schloßkasten 10 sowie die Erdungsplatte 13 zum Türblatt gegeben. Eine alternative Ausführungsform ergibt sich aus den Fig. 4, 4a, in welchen ein Schloßkasten 10 mit zwei darin laufenden Schloßstangen 11 dargestellt ist. Zwischen die beiden den Schloßkasten 10 ausbildenden Schloßkastenteile ist ein Federblech 24 eingelegt und zwischen den Schloßkastenteilen eingespannt, welches mit seitlich in die Führungsbahn für die beiden Schloßstangen 11 hineinragenden und aufgrund der Federvorspannung des Federbleches 24 in Anlage an den Schloßstangen gehaltenen Federvorsprüngen 25 versehen ist. Aufgrund der Vorwölbung des Federbleches gelangt dieses bei dem Zusammenfügen der beiden Schloßkastenteile in eine Strecklage, so daß die federnde Anlage der FedervorSprünge 25 an den Schloßstangen einerseits, wie aber auch eine dauerhafte Anlage des Federbleches 24 an den leitenden Teilen des Schloßkastens 10 gewährleistet ist.In Fig. 3, a first embodiment of the additionally provided grounding measure for the at least one lock rod 11 is shown, wherein a flat ribbon spring 21 is arranged in a wall 28 of the guide channel for the lock rod, here the cover, which ends 22 in openings 23 in the wall 28 of the lock case 10 is hooked and fixed. As can be seen from Fig. 3a in detail, the ribbon spring 21 is bent toward the inside of the lock case 10, so that it is held in force by its spring tension in contact with the end face of the lock rod 11 running in the lock case 10. This provides a secure ground connection from the locking rod 30 via the lock rod 11 and the lock case 10 and the grounding plate 13 to the door leaf. An alternative embodiment results from FIGS. 4, 4a, in which a lock case 10 with two lock rods 11 running therein is shown. A spring plate 24 is inserted between the two lock case parts forming the lock case 10 and clamped between the lock case parts, which is provided with spring projections 25 which project laterally into the guideway for the two lock bars 11 and are held in contact with the lock bars due to the spring preload of the spring plate 24. Due to the protrusion of the spring plate, this comes into an extended position when the two lock case parts are joined together, so that the resilient contact of the spring projections 25 on the lock rods on the one hand, but also permanent contact of the spring plate 24 with the conductive parts of the lock case 10 is ensured.
